Add an AI support agent to your Wix site.

A chat on every page of your Wix site that answers from your docs, shows the passage it used, and hands what it can’t answer to you.

Before you start.

  • On Wix

    Your site must be published and have a connected domain.

  • On hiy

    A Support Agent. Making your first one starts a 14-day free trial, no card needed, one per account.

    Make one from your site

  • Who can ask it

    Anyone, even a script, can ask an open agent, so treat what it knows as public.

    Open on your site

  • Visitors who sign in

    Leave it closed and have your own server sign each visitor a token instead.

Step by step.

Three steps in hiy, 4 on Wix, then a test.

In hiy

  1. Add your site in hiy

    In your Support Agent, on the Install card, type your site’s address and press Save.

  2. Switch on Open on your site

    It asks you once before it opens. Anyone on your sites, even a script, can then ask it, so treat what it knows as public.

  3. Copy the line

    Copy the one line it shows. data-twin names your agent.

    <script src="https://hiy.ai/embed.js" data-twin="your-agent" data-mode="bubble" async></script>

On Wix

  1. Open Custom Code

    In your site’s dashboard, go to Settings, then Custom Code under Development & integrations.

  2. Add the line

    Press + Add Custom Code, paste the line and give it a name you’ll recognise.

  3. Choose all pages, at the end of the body

    Under Add Code to Pages choose All pages, and under Place Code in choose Body – end.

  4. Apply

    Press Apply.

Then

  1. Test it on your live site

    Open a page of your published site and ask something your docs answer, then something they don’t. hiy opens only on https pages of the sites on your list.

Checked 16 October 2026 against Wix’s own help:

Worth watching for.

  • Snippets belong to a domain: if you assign a different domain to your site, Wix deletes them.
  • Wix doesn’t support third-party snippets, so if the line misbehaves, write to us at [email protected].

Train it on your Wix site.

In hiy, go to Agents, press New Support Agent, paste your site’s address and press Find its pages. It lists the pages and reads none of them until you create the agent, and Choose pages unticks pages or adds links.

When the site changes, open it in Knowledge and press Re-sync now, or have it re-read weekly or monthly. New pages are offered, never added.

Questions people ask first.

Do I need a developer to add hiy to Wix?

No. You paste one line into a Wix custom code snippet and save, and hiy needs no server of yours.

Is my agent’s knowledge public on my Wix site?

With Open on your site switched on, yes. Anyone on the sites you list can ask it, and so can a script, so treat what it knows and its instructions as public.

What if my visitors sign in?

Leave Open on your site off and have your own server sign each visitor a short-lived token instead. The chat API guide shows how.

Put it on your own site. Start free; the paid plan is free for 14 days.
